    Make DRL Turn On With Parking Lights

    UPDATE: I finally got around to installing the new headlight housings over the holiday weekend, and I gotta say, I'm thoroughly impressed with both the look and light output/beam pattern at night. I kinda rushed the installation and ended up using the tap splice connectors that came in the box...

    In what situations have you used 4L/4Low?

    This may not be relevant to the newer models, but I've used 4L a handful of times in my '03 Tahoe. There are some moderately challenging trails on the outskirts of my town that I go to every now and then. The trails are just barely wide enough for my truck, and there are some gnarly rocky slopes...

    How to Reset Transmission Control Module?

    I'm no expert in drivetranes, but in my experience with metals as a machinist, it's not shocking to me that a hardened shaft would break. I had a taper pin shear on an old (1980s) Zocca surface grinder at work. (this machine is the size of an NYC apartment and has a very large ball screw that...

    How to Reset Transmission Control Module?

    About a third of it broke off. It a came right out but the broken-off bit was tangled into the remaining spring. Miraculously, there wasn't any significant scoring on the cylinder wall

    How to Reset Transmission Control Module?

    It's funny you say that, because before, if I had it in tow/haul, it would BANG into 2nd, neck jerking as you say. But in regular drive it would be sloppy. The shifts now are firm and quick in a good way, but not as jarring as before if it was in tow/haul

    How to Reset Transmission Control Module?

    Hmmm... Well maybe it had nothing to do with the broken spring, but prior to doing this, the 1-2 was pretty bad. It would shift, then a second later it would jerk, almost as if it had just fully grabbed. I'm no expert, but to me it seemed like the engagement was pretty delayed.

    Yes, I drilled the 1-2 hole to .070

    How to Reset Transmission Control Module?

    OK thanks, I'll check that this weekend. The servo kit came with 2 shims and I installed 1. I kinda breezed thru the servo install because it was a long day doing the shift kit and I was burned out lol You both are right, after reading through the instructions, the kit does not say to do that...

    How to Reset Transmission Control Module?

    Ngl, I have no clue about the travel lol I just put it in the same way the other one was. Now that you mention it tho, that sounds important. Where do I measure this travel? And as for the accumulators, yes I used Sonnax. Ok, ill disconnect the battery just for hahas. I have no complaints with...

    How to Reset Transmission Control Module?

    Hey guys, sorry for the dumb question, but I've searched the forum several times as well as Google and haven't found an answer. Can anyone tell me how to reset the TCM, hopefully without a scan tool? I just installed a shift kit and corvette servo, as well as replaced the shift accumulators in...

    Make DRL Turn On With Parking Lights

    I will definitely update the thread when I get around to doing it, probably won't be for a while tho. As far as the LEDs, they are sealed in the housing. They can be replaced, but not easily. It would require disassembling the housing and desoldering/replacing the individual lights on the...

    Make DRL Turn On With Parking Lights

    That's a good point. I had considered a relay, but it wouldn't be as cool because they wouldnt come on when I unlock with the keyfob

    Make DRL Turn On With Parking Lights

    I appreciate you taking the time to help. I managed to get ahold of a more complete set of wiring diagrams, and it looks like both the DRL/parks are controlled by separate relays in the BCM. Now that I know there's no electronic funny business involved, I'm gonna go with my original plan of...

    Make DRL Turn On With Parking Lights

    Yes, they're flying leads that need to be spliced. I would prefer to retain normal functionality of park/drl, just with the addition of the bars for both. I know the parking lights are controlled by a relay in the BCM, but what about the DRL? My only worry is if the the DRL control is...

    Make DRL Turn On With Parking Lights

    I just purchased a set of Spec-D headlights with the DRL LED fiber optic bar for my 2003 Tahoe. The way they're meant to be installed is tapping into the DRL wiring, but I want the bars to illuminate when the parking lights are on too. Basically I'm looking to have them act as DRL, but also be...

    '03 Tahoe 5.3/4L60/NP246 Swap to 6.0/4L80

    So you know exactly what I mean! At the bare minimum I'd like to ditch the slosh box. Sure it'd be cool to have a little extra power, but the trans alone would be an absolute godsend. Unfortunately the Tahoe has a 1 piece driveshaft (although I haven't gotten underneath the donor to see what it...

    '03 Tahoe 5.3/4L60/NP246 Swap to 6.0/4L80

    Side note: I would not be opposed to swapping only the transmission if possible. Not sure if a 4l80 will bolt to a 5.3... After driving the donor I couldn't believe how quick and firm the shifts were! Makes the 4l60 feel like a real slosh box lol

    '03 Tahoe 5.3/4L60/NP246 Swap to 6.0/4L80

    Thanks for the reply! I did not know the input spline was a different size, good to know. Rear drive shaft is 1 piece. I'll have the entire complete donor truck so whatever needs to change won't be an issue as long as it fits the Tahoe chassis. I kinda figured the drive shaft was gonna be an issue

    '03 Tahoe 5.3/4L60/NP246 Swap to 6.0/4L80

    I have an '03 Tahoe with the 5.3 Flex, 4L60E, and NP246 (auto 4wd) transfer case. I have the opportunity to buy a low mileage rusted out truck for parts and I'm wondering how straightforward it would be to swap the drivetrain from the junker into my Tahoe. The donor is an '06 Silverado 2500 HD...

    Coolant Reservoir Level Sensor

    Lol I used to work at the shop that did it. They definitely used generic green. I'm sure there's gonna be some sludge.

    Coolant Reservoir Level Sensor

    That's what I was thinking, thanks for confirming. I guess I'll replace the reservoir then. Gotta have the system flushed anyway. I had all the fluids changed before a 3k mile round trip drive I made earlier this year. The genius at the shop I went to used green antifreeze. The next day it was...

    Coolant Reservoir Level Sensor

    The past couple days I've been getting a low coolant message when I start my '03 Tahoe. The level in the reservoir is good and temp has been normal. Assuming the sensor is going bad. My question is, can the sensor be replaced or is it molded into the reservoir? I searched online for the sensor...

    Headlight Housing Recommendations?

    Update: turns out I won't be receiving the headlights. The guy took my money, tried to pretend he didn't receive the payment. Then when I called him out on his BS he blocked me. Some people really suck...
